Brian S Fayetteville , AR February 14, 2020 Appliance: Whirlpool 30" Sealed Gas Cooktop GLT3057RB01 Whirlpool Cooktop Glt3057rb01: Ignitors on fromt two burners were not working. How to replace Cooktop Torx Screw. I received a bid to repair the stove for $500. I decided that it might be best to buy a new one as it was about $800. I did some research and watched the repair video. I removed the glass top and realized it was a simple wire harness that had burned out on one valve. I ordered the part on Sunday and it arrived on Tuesday. When I got home from work the repair took me about 20 minutes from start to finish and it cost me under $50.
